Spiritual Warfare: 'Harassed by Satan?'

Lord, I know You can use anything - seen or unseen - to put me in my place or lead me to a deeper understanding of Your sovereignty. Forgive me for limiting Your work in the past by making assumptions that may not be true. I thought my faith made me immune to demonic attack, but if You allowed this - even ordained it - in Paul's life then there's nothing to prevent You using it in mine. I submit to Your plan, Lord, so please use whatever is necessary to humble me before You and cause me to be faithful and develop me into a useful servant for your work in the world. In Jesus' name, Amen.
